Introduction to Weather Resistance of Photochromic Powder

The lightfastness, heat resistance, and aging resistance of reversible photochromic powder are far inferior to those of ordinary pigments. Therefore, you should pay attention to the following during use:

    • Lightfastness: Photochromic powder has poor lightfastness and will quickly fade and fail when exposed to strong sunlight. It is only suitable for indoor use. To extend the service life of the discolored paint, avoid exposure to strong sunlight and ultraviolet light.
    • Heat resistance: Avoid working at temperatures above 75°C for a long time.

The exposure time of photochromic powder when used in different resins is different. The continuous exposure time may only be 5-12 hours, and the discoloration effect will be greatly weakened. However, when used indoors at room temperature, the discoloration effect can last for several years. For example:

    • If exposed to the sun for 10 minutes a day, it can be used for two years.
    • If exposed to the sun for 15 minutes a day, it can be used for a year and a half.
    • If exposed to the sun for 20 minutes a day, it can be used for a year.
    • If exposed to the sun for 25 minutes a day, it can be used for three months.

Note: The above exposure life should be judged based on the actual application. The service life of each product will be different depending on the usage environment and temperature.
